What is a Air curtain?

The air curtain has the effect of preventing cold and warm air from leaking from the entrance and exit of the building, and also preventing insects, pollen, dust, etc. from entering the room from the outside. Since the air curtain can keep the interior clean without obstructing the entry and exit of people as a truly invisible curtain, using the air curtain at restaurants makes it possible to take measures against smoke separation without a feeling of blockage. In addition, since it is possible to keep the indoor cool and warm air by shutting off the outside air even when the doorway of the building is open, there is no problem even in the work that requires transportation (for example, when used in a large refrigerating facility, the cold air is released. It also saves energy because it does not leak). In order to maintain the charge of the human body at a safe level, it is necessary to release the generated static electricity to the floor within several hundred ms and suppress the charge potential of the human body to several tens of volts or less.
